Touré plays the race card, denies the existence of a race card

Touré Neblett, co-host of The Cycle on MSNBC (we had to look that one up), took to Twitter to put conservatives in their place regarding Amb. Susan Rice and the criticism she has received from Sens. John McCain and Lindsey Graham. Touré, who recently attacked McCain and Graham as “old, white, establishment folks,” denied the existence of a race card and then accused whites of using it to intimidate African Americans.

Why is it only Black people are said to play a race card? Why is "race card" only said by whites? To intimidate Blacks from mentioning race?
